19. The calibration curve equation for quantifying
standard was I = 51.00 x [
] + 1.00, where Iis the intensity and the
concentration is in micromole/L. The reagent blank, measured by threerepeated experiments, gave a value of 0.30± 0.04. What is the detection limit for Cu2t based on asignal-to-noise ratio of 2? (A) 1.56 nM. (B) 1.35 nM. (C) 2.56 nM. (D) 2.35 nM.
